Bday Gift Ideas for 6 Year Old Boy

Cant really go wrong with Hot wheels.
Or a deck of playing cards.
Or a cute board game like Hi-Ho Cheerio or Operation (my boys love that one).
Or a cute movie, scooby-doo, or Bugs Bunny or Tom and Jerry?

Legos
Hex bugs
Nerf
Hot Wheels

The boys on my street are into Pokemon cards. I also like the idea of board games - Sorry Sliders, Operation etc.

I'm not sure about cost, but Hex Bugs are really big right now. Or some kind of Lego set if he's into Legos.

I have 3 boys and a girl. One of my boys is almost 6 and into Mario everything. He also likes Ninjagos (lego-based) and Beyblades. These are a bit more popular with the 8-10 age crowd, but will quickly be there!

We found the Hex bugs were short-lived fun.

Ninjago starter set is $20

Beyblades you can get at Target and run about $8. Get two, so he can battle with someone.

Order wood figurine toys from Padilly from the Holztiger brand. I've been buying two items for each b-party I have been going to. Dinosaurs. Whales. Dolphins. King and Queen. Knight and horse. Wolves. Tigers and lions. Bears. Love 'em.

My 6 year old just got:

Legos - loves them
Hex bugs - we have 3, he has played with them for a year. They are really cool - especially if you look at the robotic science behind them.

Zoob - cool building toy
Cards - matching memory game sort - likes them
Playmobil - has been great. He just got the cafe and bakery along with a meerkat set and rhino.

I see no reason these would be inappropriate for a boy or girl.

All ideas below are great. I'll add movie tickets, art supplies (crayola has some neat stuff), sports equipment? (soccer ball, baseball/bat)

My 6 yo son just got an umbrella, Lego water bottle, harmonica, and backscratcher for his birthday/Christmas. He loves each one of them and still plays with them, even a week after Christmas! lol

You can't go wrong with books either. Any kind of encyclopedia of some sort - Encyclopedia of Gross Things/Animals/Weather/Inventions that failed/Superheroes - would be good.
